Answer:
2/13 or 15.38%
Step-by-step explanation:
Number of Aces in a deck = 4
Number of 7s in a deck = 4
Number of cards in a deck = 52
Probability of A or 7 = (4 Aces + 4 Sevens) / 52 cards 8 cards / 52 cards
This simplifies to 2/13 or 15.38%
Answer:
n≅376
So sample size is 376.
Step-by-step explanation:
The formula we are going to use is:
where:
n is the sample size
p is the probability of favor
q is the probability of not in favor
E is the Margin of error
z is the distribution
α=1-0.98=0.02
α/2=0.01
From cumulative standard Normal Distribution
p is taken 0.5 for least biased estimate, q=1-p=0.5
n≅376
So sample size is 376
Answer:
Just restart your computer
To solve for the value of the residues A, we can use the
formula:
<span>A^2 = 1 (mod
prime)</span>
This is only true for prime numbers. The given number
which is 317 is a prime number therefore the values of the residues A are:
A = + 1, - 1
Since I believe the problem specifically states for the list
of positive integers only and less than 317, a value of A = - 1 is therefore
not valid. However, a value of – 1 in this case would simply be equal to:
317 – 1 = 316
<span>Therefore the residue values A are 1 and 316.</span>
